I believe that using characters other than the ones mentioned above as a Label will not cause an error,
but I think the Operators will not be able to handle it correctly based on the following code.

https://github.com/NetApp/trident/blob/master/storage_attribute/label.go#L14-L19

I would also appreciate it if the permissible characters could be explicitly stated.

Thanks.
